The northernmost of the two lamps that first lit the world (S/35). The meaning of this name is unclear.
Conceptual Development: In Silmarillion drafts from the 1930s, the name of this lamp was ᴹQ. Helkar (LR/32). In the 1950s, Tolkien changed this to Foros and then Forontë (both probably from the root ᴹ√PHOR “right hand, north”) before settling on Ormal (MR/7).
Illuin place-name, name of one of the Lamps of the Valar; apparently incorporating the element luin "blue" (Silm): hence *"all-blue"?
